WebView polling breaks on Android 15 after opening Chrome Custom Tabs

WebView polling breaks on Android 15 after opening Chrome Custom Tabs

I'm encountering an issue where polling in a WebView stops working on Android 15 after opening Chrome Custom Tabs. The polling works perfectly fine on Android 14 and below, but once I open Chrome Custom Tabs, the XMLHttpRequest goes into a pending state and no API response is received.

Steps to reproduce:

  1. I have a simple HTML page (pollingtest.html) with a JavaScript polling mechanism that makes an API call every second to fetch data.

    pollingtest.html

    <!DOCTYPE html>
<html>
<body>

<div id="demo">
    <h1>The Polling Test Android</h1>
</div>

<script>
    // Function to make the API call and update content
    function getValue() {
        var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("demo").innerHTML = this.responseText;
                console.log("API Response:", this.responseText);
            }
        };

        // Fetch the data every 1 second
        xhttp.open("GET", "https://api.coindesk.com/v1/bpi/currentprice.json", true);
        xhttp.send();
    }

    // Start calling the API every 1 second as soon as the page loads
    window.onload = function() {
        setInterval(getValue, 1000);  // Call getValue every 1000ms (1 second)
    };
</script>

</body>
</html>

  2. The HTML file is loaded into a WebView using the following code:

    webview.loadUrl("file:///android_asset/pollingtest.html");

  3. After 5 seconds, Chrome Custom Tabs is opened using the following code:

    new Handler(Looper.getMainLooper()).postDelayed(() -> {
    startChromeCustomTabs(); // starts chrome custom tabs after 5 seconds
}, 5000);

After opening Chrome Custom Tabs on Android 15, the XMLHttpRequest in the WebView stops, and the network request enters a "pending" state, as seen in the Chrome network inspector.

The issue only occurs on Android 15; on Android 14 and below, everything works as expected.

My question:

Is there a known issue with WebView polling in Android 15 that causes network requests to hang when Chrome Custom Tabs is opened? Is there a workaround or solution to ensure the polling continues to function correctly after launching Chrome Custom Tabs?

Any help or guidance would be greatly appreciated!
